What do the warnings I get during installation mean?

[Amandeep Gautam]

I am trying to install grpc on AIX. I get a few warnings towards the end. What do they mean? What will be the implications?

Foloowing is the gcc version:

go version go1.9 gccgo (GCC) 8.0.0 20171205 (experimental) aix/ppc

Below is the installation log:
